Subject: [PATCH 0/2] perf tools: Add support for PERF_RECORD_SWITCH to Intel PT
Date: Thu, 13 Aug 2015 12:40:55 +0300 [thread overview]
Message-ID: <1439458857-30636-1-git-send-email-adrian.hunter@intel.com> (raw)
Hi
Support to enable unprivileged users to see context switches
of their own processes has recently been added to the kernel.
These patches enhance Intel PT support to take advantage of that.
The patches apply on top of the other Intel PT perf tools patches.
